Features

John Deere has engineered the PowerTech PSS 13.5L (824 cu. in.) engine to meet the high expectations for fuel economy and performance that operators expect.

Selective catalytic reduction (SCR) is an exhaust filter option that reduces NOx emissions. SCR technology increases in cylinder combustion temperatures to reduce particulate matter (PM) output but as a result of these higher combustion temperatures, it increases the NOx (smog) emission levels. To keep the NOx levels within acceptable standards, a urea-based additive, sometimes referred to as AdBlue® system or diesel exhaust fluid (DEF) is added into the exhaust stream to low NOx emission downstream of the engine. The urea mixes with engine exhaust gases in the catalytic converter. The resulting reaction of adding urea (NH3) (or purified fertilizer) into the exhaust stream and passing through a catalyst transforms the NOx which results in harmless nitrogen gas and water vapor.

Series turbochargers

Series turbocharging delivers higher power density, improved low-speed torque, and improved high-altitude operation. By splitting the compression of the charge air between two turbochargers, both can operate at peak efficiency and at slower rotating speeds. This lowers stress on turbocharger components and improves durability.

Series turbocharging works when fresh air is drawn into the low-pressure turbocharger (fixed geometry), where air pressure is boosted. This pressurized or boosted air is then drawn into the high-pressure turbocharger (VGT or WGT), where air intake pressure is further raised. The high-pressure air is then routed to an air-to-air aftercooler, where the air is cooled and routed to the engine’s intake manifold.

Fresh air is first drawn into the low-pressure fixed geometry turbocharger and compressed to a higher pressure. The compressed air is then drawn into the high-pressure VGT where the air is further compressed. The compressed air is then routed to the charge air cooler, and then to the intake manifold. By splitting the work between two turbochargers, both can operate at peak efficiency and at a slower rotating speed.

VGT

The VGT is electronically controlled and hydraulically actuates the turbo vanes as required to maintain peak engine performance.

VGT vanes in exhaust flow

The turbocharger’s vanes are in the exhaust flow. The opening or closing of the vanes changes the outlet volume and airflow speed against the turbocharger impeller. When exhaust flow is low, the vanes are partially closed. This partial closure increases the pressure against the turbine blades to make the turbine spin faster and generate more boost pressure. The ability to keep the airflow flowing at optimum levels provides more consistent engine boost pressure and the ability to respond to load quickly across the entire engine rpm range. This system is without turbo lag as can be found on some engines. Boost pressure in the intake manifold is controlled at its optimum point for added fuel economy and performance regardless of rpm or load.

The overall benefits:

Increased low rpm torque

Quicker response to load

Increased peak torque

Improved fuel economy

Improved performance at high altitudes

Air-to-air aftercooling

Air-to-air aftercooling lowers the intake manifold air temperature and provides more efficient cooling while reducing cylinder firing pressure and temperatures for greater engine reliability. Since low temperature air is denser, a higher volume of air flows into cylinders so the engine is capable of meeting the increasing horsepower demands.

The single fuel rail is a drilled passage in the head, eliminating the need for external lines for reduced service through the fuel filter

The electronic control unit monitors various sensor inputs from the tractor and automatically changes the sheave ratio to change the fan speed. Hydraulic oil pressure is directed to the pistons that push the top inner sheave out (A), to close the gap and create a larger working diameter.

The bottom sheave (B) responds by compressing the coil spring, widening the gap between the two sheave halves, and creating a smaller working diameter to increase the fan speed.

To slow the fan, the valve opens, allowing oil to leave the piston, widening the upper sheave halves.

Automatic shutdown function

This feature monitors engine coolant temperature, engine oil pressure, and transmission oil pressures while the transmission is in the park position, and the operator is out of the seat. If any of the systems reach undesirable levels, the tractor will shut down, to help prevent further tractor damage.

Engine control unit (ECU) - full authority electronic controls

This engine control unit uses signal inputs from sensors and pre-programmed performance modeling to control critical engine functions such as fuel quantity, injection timing, air-to-fuel ratio, multiple fuel injections, amount of cooled exhaust gas recirculation (EGR), and a host of other control parameters to deliver peak fuel economy and engine performance.

Each injector is controlled individually by the ECU. The ECU turns the injector on and off during each firing cycle to control the fuel delivery into each cylinder. The ECU can sense engine speed and load changes at a rate of 100 times per second and respond instantly to them. Load and speed sensing allows each cylinder’s fuel delivery rate to be adjusted independently at the individual injector. With each injection cycle, the ECU can make the following adjustments on the go:

Number of injections

Fuel pressure in the common rail

Start of injection

Duration of injection

This management system is connected to the transmission allowing the engine and transmission to respond simultaneously.

Cold weather and high altitude compensation are also precisely controlled for quality starts regardless of weather and proper power levels at high elevations.

Noise reduction

The injection system also contributes to the engine running at a decreased noise level by a process called pilot injection. The precise fuel injection capabilities allow a small amount of fuel to be injected early in the combustion process. This helps lessen the combustion knock that is commonly heard on many diesel engines. While the combustion noise reduction is most obvious at lower engine speed, pilot injection continues to function at any engine speed.

Vari-Cool™ system

9R cooling package

The Vari-Cool fan drive system precisely controls the speed of the fan in relation to the cooling requirements to maximize efficiency of the engine. The Vari-Cool system is efficient for two primary reasons:

The belt drive used in the Vari-Cool system transfers almost 100 percent of the power from the engine to the fan.

The variable fan speed sheave is electronically controlled only operating at the necessary speed to cool the engine and other auxiliary components.

Vari-Cool is integrated into the hood design

The Vari-Cool system is an integrated part of the hood design. Intake and outflow of air from the coolers is diverted to key openings in the hood structure. The design allows for airflow dispersion that lessens dust and crop kick-up by discharging the airflow away from the cab.

How Vari-Cool works

This electrohydraulic system uses variable speed drives. Actual fan speed is determined by the ratio differences of the top fan drive sheave to the bottom sheave.

e18-speed PowerShift Transmission (PST) with Efficiency Manager™

PowerShift Transmission with Efficiency Manager lever

Designed for the 9R Series Ag and Scraper Tractors, the 18-speed full PowerShift transmission with Efficiency Manager is optional on the 9360R-9460R (order code 1492) and standard on the 9510R and 9560R. The 9R Series Ag and Scraper Tractor transmission features include:

Eighteen forward speeds and six reverse speeds

Able to shift from neutral up to 13th forward

Speed matching from 18th forward to 13th forward

Clutchless shuttle-shifting between 13th forward and sixth reverse

Speeds are carefully spaced to take full advantage of engine power bulge and torque characteristics

Ten speeds with a 0.8 kph (0.5 mph) speed change between gears in the 5-13 kph (3-8 mph) working range

Allows selecting the right gear for the operation to ensure that best fuel economy and productivity are obtained

Speeds carefully developed to match all of the tractor's needs

Transmission-to-engine controller communication

The 9RT offers increased speed up to 40 K/h (25 mph). Gear ratios on the track tractors have increased approximately 16.5% across the board providing increased speed at respective levels on the 9030T.

High-flow hydraulics, 435 L/min (115 gpm) system

Dual hydraulic pump system

Selective control valve (SCV) stack

Optional high-flow hydraulics are available on 9 Family Tractors by ordering code 3270. The high-flow hydraulic system provides an additional 215 L/ min (57 gpm) of flow for a total of 435 L/ min (115 gpm). This system is ideal for hydraulic fan motor demands. This system is recommended for agricultural implements with continuous flow requirements. When maximum hydraulic pump capacity is reached, multiple functions will continue to operate at the same proportional flow rate.

The 9 Family Ag High-Flow Tractors have two parallel hydraulic systems. The benefit of this system is that functions can be split between the two systems. Functions that require high flow and low pressure can be combined on one system (for example, air seeder fans, and planter motors). Functions that require high pressure and low-flow can be connected to the remaining system (for example, implement lift, fold, and constant down-pressure systems).

Following these guidelines allows the hydraulic system to run cooler as it prevents both hydraulic pumps from running at high pressure. In general, pumps forced to run at both high pressure and high flows generate much more heat than a pump running at a lower flow or lower pressure.

The system operates with two hydraulic pumps:

Pump 1 - provides hydraulic flow of up to 215 L/min (58 gpm) to SCVs 1, 2, and 3. These SCVs are useful for operating lift/lower and other cylinder type hydraulic needs.

Pump 2 - attaches in front of pump 1 and provides hydraulic flow of up to 215 L/min (57 gpm) to SCVs 4, 5, and 6. These SCVs are useful for operating hydraulic motors to drive air/fan or vacuum systems on seeding/planting equipment.

Hitch controls

3–point hitch controls under armrest on CommandARM

To help boost productivity, a field-installed kit with 3-point hitch controls can be purchased. If this option is selected, control buttons will be located on the 9 Family Tractor’s CommmandARM to access individual hitch settings. There are three buttons — set, lock, and load depth. There is also a rotary encoder that allows for finite movements of the hitch. The rotary encoder is detented, so it clicks for each movement. Additionally, hitch adjustment controls are located under the CommandARM for raise/lower rate.

Hitch load depth

The load depth feature is a useful tool designed to increase performance in tillage applications. Load depth adjustments allow the operator to make adjustments to hitch draft responsiveness.

Draft control helps maintain the operating depth in varying conditions, such as rolling terrain, and varying soil densities.

An additional feature with load depth control is the hitch slip option. Hitch slip uses wheel slip data to supplement the draft control system. If the wheels slip, the 3-point hitch lifts to allow the tractor wheels to maintain traction with the ground. Once the slip condition is no longer present, the hitch lowers to the required depth as determined by the hitch command and load depth settings.

Both of these hitch command options are easily programmable in the CommandCenter display by pressing the load depth shortcut key, followed by using the thumbwheel and confirm key to dial in the desired settings.

Hitch, external remote control switch

3-point hitch switch on fender of 9R

For added operator convenience, a 3-point hitch remote control switch is located on top of the left rear fender for 9R, 9RT, and 9RX Tractors. The external remote switches enable the operator to raise and lower the 3-point hitch from behind the tractor while hooking to implements.

9R/9RT e18™ with Efficiency Manager™

Efficiency Manager thumbwheel

Efficiency Manager switch

What is it?

Efficiency Manager allows for IVT™-like operation on the 18-speed PowerShift transmission. With Efficiency Manager engaged, the operator no longer has to manage the engine revolutions per minutes (rpm) and gear selection for the most efficient level of operation possible. Efficiency Manager does that automatically by shifting up and throttling back depending on the load on the tractor.

How does it work?

With the tractor sitting still, in neutral, or once the tractor is in motion, the operator simply pushes either the F1 or F2 switch on the CommandARM™ to activate the feature. Once Efficiency Manager is activated, the operator can set and adjust the desired ground speed by using the thumbwheel on the shift lever. An icon and the desired ground speed will appear on the corner post display once Efficiency Manager is activated.

The operator can program two ground speeds by pushing either the F1 or F2 switch. The F1 setting will typically be set for field work while the F2 setting will be used for field/road transport. F1 can be set at any speed from 2 mph (3.2 km/h) to 12.6 (20.3 km/h) mph, and F2 can be set at any speed from 2 mph (3.2 km/h) to 25 mph (40 km/h).

Can it be managed by the operator?

By navigating through the CommandCenter™, the operator can adjust the rpm shift points while operating in custom mode. The operator can set it to automatic or custom. In automatic mode, the tractor will predict the optimum shift points under load to maintain the highest level of performance and operation. Custom mode allows the operator to adjust how high or low he/she would like the engine rpm to pull down before shifting under load. See the operator’s manual for more information.

Operation example:

If a customer is operating a 9R, equipped with the 18-speed PowerShift transmission, on a grain cart he/she could set F1 to the same speed as the combine for an unload, on the go scenario. Once the combine is empty and the 9R operator is ready to unload the grain from the cart onto the truck, he/she could push the F2 switch (already set at a higher transport speed) to get them to the truck quicker.

NOTE: Efficiency Manager is not recommended during for use during high draft load applications. We do not recommend the use of EM during the cut cycle in scraper applications. Efficiency Manager is recommended during the transport cycle of scraper applications.
